A Quenched Disorder in the Quantum-Critical Superconductor CeCoIn₅.

ABSTRACT: Emergent inhomogeneous electronic phases in metallic quantum systems are crucial for understanding high-T_c superconductivity and other novel quantum states. In particular, spin droplets introduced by nonmagnetic dopants in quantum-critical superconductors (QCSs) can lead to a novel magnetic state in superconducting phases. However, the role of disorders caused by nonmagnetic dopants in quantum-critical regimes and their precise relation with superconductivity remain unclear. Here, the systematic evolution of a strong correlation between superconductive intertwined electronic phases and antiferromagnetism in Cd-doped CeCoIn₅ is presented by measuring current-voltage characteristics under an external pressure. In the low-pressure coexisting regime where antiferromagneti
